Sunroom & Patio Enclosures in Los Angeles
Southern California's climate makes sunrooms one of the best square-footage investments available — enclosing an existing patio or building a new sunroom adds real, usable living space without the footprint of a full addition.
How We Handle Sunroom & Patio Enclosures
We build both three-season sunrooms (screened or single-glazed, used most of the year) and fully insulated four-season rooms tied into your home's HVAC or served by a dedicated mini-split. Scope includes engineered foundations or footings, roof tie-ins to your existing roofline, and glass or screen enclosure systems.
Every sunroom is permitted and engineered — this is a structural addition, not a kit assembled over a weekend. We finish the interior to match your home's existing trim, flooring, and paint so it reads as original construction, not an add-on.
Sunroom & Patio Enclosures FAQs
How much does a sunroom addition cost?
Three-season sunrooms typically run $25,000–$50,000; fully insulated four-season rooms with HVAC run $45,000–$90,000+ depending on size and finishes. Itemized estimates, always free.
What's the difference between a sunroom and a covered patio?
A covered patio (see our decks & patios page) is open-air with a roof; a sunroom is fully enclosed with walls of glass or screen, making it usable in more weather and often countable as conditioned square footage.
Do sunrooms need a permit?
Yes — sunrooms are structural additions requiring engineering and permits in virtually every city we serve. We handle the full permit process as part of the project.
